“"This paper compares the construct and predictive validity of a set of disability questions tested on a sample of respondents in five Asia-Pacific countries. It finds that the construct validity of the Washington Group questions for the seeing, hearing, mobility and self care domains is good when WHO questions for the corresponding domains are used as a benchmark; this does not, however, apply to the questions for the cognition and communication domains. The Washington Group questions perform similar to corresponding WHO questions in terms of predictive validity. For the four models examined - explaining difficulty with household responsibilities, work and school, and joining community activities, as well as employment status - the different question sets perform similar in terms of significance and magnitude of the odds ratios"
